  "account": "Singapore General Hospital (SGH) has developed an AI tool named iScreen that can detect brain bleeding from CT scans within six minutes, significantly faster than the 30 minutes to an hour currently needed by radiologists for urgent cases. The AI model identifies white spots and other indicators of bleeding in the brain, which could have severe consequences for the patient. Acute cases may require surgery to stop the bleeding. When iScreen flags a positive result, an SMS is sent to both the neuroradiologist and the attending doctor, prompting the neuroradiologist to prioritize reviewing the AI results before other scans in the queue. SGH's data shows the sensitivity of iScreen is 93.1 percent, with a 6.9 percent false positive rate. The proportion of bleeding cases taking more than an hour to be reported decreased from 14.6 percent to 5 percent with the use of iScreen. SGH's neuroradiologists, who help review CT scans, will report positive cases to attending doctors. The AI model, co-developed by Iota MedTech and SGH, aims to support radiologists rather than replace them. SGH handles thousands of CT scans daily, with around 50 head CT scans and 10 percent showing signs of bleeding. Brain bleeding, or intracranial hemorrhage, can occur due to strokes, ruptured aneurysms, tumors, or traumatic head injuries, especially in seniors or those on blood-thinning medications. Local start-up Iota MedTech has worked with NNI and SGH since 2019 to develop iScreen, with potential for further clinical applications. The model is now deployed on Singapore's national AI medical imaging platform, AimSG, enabling other hospitals to integrate it into their radiology workflows.",
